The Sonoff Zigbee 3.0 USB Dongle Plus-ZBDongle-E is based on the EFR32MG21 chipset. The EFR32MG21 chipset is renowned for its unparalleled stability. The Sonoff ZigBee 3.0 USB Dongle Plus is the best among ZigBee coordinators due to this chipset.

This ZigBee gateway serves as the central nervous system for all ZigBee devices. Stability is therefore crucial for a reliable environment. This ZigBee coordinator features the following characteristics:
- Based on the EFR32MG21 chipset
- Equipped with a robust aluminum casing that minimizes interference signals
- Cooling fins ensure that this powerhouse does not overheat
- SMA connector for antenna
- Included antenna
- Comes with Z-Stack 3.x.0 Coordinator firmware, ready to use directly within Home Assistant or Domoticz!
- +20 dBm amplification
- Can be used within Home Assistant or Domoticz via the ZigBee2MQTT or ZHA Plugin

By linking Home Assistant or Domoticz with a ZigBee coordinator, most ZigBee devices can be controlled. It is then no longer necessary to use, for example, a Philips Hue bridge, IKEA TRÃ…DFRI gateway, or Xiaomi gateway. By controlling all ZigBee devices via Home Assistant or Domoticz, privacy and security concerns with, for example, Xiaomi products are no longer necessary. All ZigBee communication will remain indoors and will no longer be routed through, for example, a Xiaomi cloud.
